ナショナルジオグラフィックさんのインスタグラム写真 - (ナショナルジオグラフィックInstagram)「Photo by @CarltonWard | Coral reefs rise close to the surface in Dry Tortugas National Park, with the historic lighthouse at Loggerhead Key in the background. Seventy miles west of Key West, Florida, this lighthouse marks the tip of a Marine Protected Area where the Atlantic Ocean and Gulf of Mexico meet. Corals here remain relatively pristine compared to reefs closer to Florida's heavily developed coastlines. But no corner of the ocean is beyond the reach of plastics pollution. I share this photograph on #WorldOceansDay as a reminder of what is at stake if we don't clean up our act. #planetorplastics.
